Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6

open access: yesAdvanced Functional Materials, EarlyView.
This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...

Unveiling Phonon Contributions to Thermal Conductivity and the Applicability of the Wiedemann—Franz Law in Ruthenium and Tungsten Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Thermal transport in Ru and W thin films is studied using steady‐state thermoreflectance, ultrafast pump–probe spectroscopy, infrared‐visible spectroscopy, and computations. Significant Lorenz number deviations reveal strong phonon contributions, reaching 45% in Ru and 62% in W.

Cat‐Vibrissa‐Inspired Biomass Fiber Aerogels for Flexible and Highly Sensitive Sensors in Monitoring Human Sport

open access: yesAdvanced Functional Materials, EarlyView.
Inspired by cat vibrissae, biomimetic biomass PHFs/SA aerogels (BFAs) are developed via precursor‐assisted in situ polymerization and freeze‐synergistic assembly. These ultralight, porous pressure sensors exhibit high sensitivity and excellent durability, enabling pulse detection, handwriting recognition, Morse code transmission, and notably real‐time ...
